$\}$Three integers are read from input as variables student$1$ to student$3.$ Declare a vector of integers named studentListings and initialize the elements at the even indices with the value $0$ and the odd indices with the variables student$1$ to student$3$ in the order the input integers are read.

Ex: If the input is $263331,$ then the output is:

$026033031$

Note: Index $0$ is considered an even index.
